+# CCCL - Continuous Integration (CI) Workflow 
+As a header-only C++ library, the code we write isn't compiled until a developer includes it in their project. 
+
+This means our code needs to be robust enough to compile and run across a variety of platforms, compilers, and configurations. 
+As such, maintaining extensive and thorough Continuous Integration (CI) coverage is crucial. 
+
+Our CI system needs to test various combinations of operating systems, CPU architectures, compilers, and C++ standards. 
+The number of configurations can be quite large and hence our CI system must be designed to handle this complexity. 
+We use GitHub Actions for this purpose. It is flexible, powerful, and well-integrated with GitHub.
+
+This document will walk you through our CI workflow and guide you on how to interact with and troubleshoot it when needed.
+
+## Workflow Overview
+
+### TL;DR
+
+```mermaid
+graph LR
+    A[Workflow Starts on Push to PR]
+    A --> B{Computes Matrix}
+    B --> C[For Each Matrix Configuration]
+    C --> D{Runs a Build Job}
+    D --> E[Build Job Completed]
+    E --> F{Runs a Test Job}
+    F --> G[Test Job Completed]
+    G --> H[CI Successful]
+```
+
+This repository relies on a GitHub Actions-based Continuous Integration (CI) workflow. Here's what you need to know:
+
+- **Trigger:** The main workflow triggers on every push to the main branch or pull request (PR).
+- **Execution:** The workflow generates a matrix of build configurations, based on the settings in matrix.yml, and then dispatches separate build and test jobs for each configuration. 
+- **Failures:** If a job fails, you'll be notified through GitHub's interface. You can then check the logs for details.
+- **Recovery:** To handle job failures, pull the relevant container image and rerun the script locally to reproduce the issue.
+
+### The Matrix
+
+The matrix defined in the [`matrix.yml`](ci/matrix.yaml) is the single source of truth for the environments we test our code against.
+It dictates the build configurations, such as CUDA version, operating system, CPU architecture, compiler, GPU architectures, and C++ standards. 
+It allows us to test our code against different combinations of these variables to ensure our code's compatibility and stability. 
+
+### Build and Test Jobs
+Our CI workflow primarily revolves around two major types of jobs: build jobs and test jobs. 
+
+#### Build
+Build jobs compile our unit tests and examples in various environments, mimicking the conditions in which our users might compile the code. 
+These jobs simply invoke a build script (e.g., `build_thrust.sh`) which contains all the necessary steps to compile the code.
+
+The advantage of this approach is two-fold. 
+First, it allows us to keep our CI configuration files clean and focused on the orchestration of jobs rather than the specifics of building the code. 
+Second, it greatly simplifies the process of reproducing build issues outside of CI. 
+Developers can run the build script locally, in their environment, and the build will behave in the same way it does in CI.
+
+#### Test
+After the build jobs have successfully compiled the test binaries, the test jobs run these binaries to execute our tests. 
+On first glance, you may notice that the test jobs are rebuilding all of the test binaries. 
+However, we are relying on sccache to cache the build artifacts from the build jobs and reuse them in the test jobs.
+
+Similar to the build jobs, test jobs use a script (e.g., `test_thrust.sh`) to define the steps required to execute the tests.
+If a test fails in CI, developers can simply run the script in their local environment to reproduce the issue and debug it.
+
+The syntax of the build and test scripts is the same:
+```bash
+./ci/build_thrust.sh <host compiler> <c++ standard> <gpu architectures>
+./ci/test_thrust.sh <host compiler> <c++ standard> <gpu architectures>
+
+#examples
+./ci/build_thrust.sh g++ c++17 70;80;86
+```
+
+In summary, the heart of our build and test jobs is the corresponding build or test script. 
+This design philosophy helps maintain a clear separation between CI orchestration and the specifics of building and testing. 
+Moreover, it paves the way for straightforward issue reproduction, thereby aiding developers in their debugging process.
+
+## Lifecycle of a Pull Request
+
+From creation to merging, a pull request in this project follows these steps:
+
+1. Create a PR: Once you make a change, open a PR. 
+    - If you have write permission to the repository, CI workflow will automatically start.
+    - If you don't have write permission, the workflow will start once a maintainer comments on the PR with `/ok to test`. This comment is required for all subsequent workflow runs.
+2. Wait for results: GitHub Actions executes the defined CI workflow, running jobs based on the matrix configuration.
+3. Interpret results: Check the status of the workflow. If it passes, all tests have passed on all defined configurations, and your changes likely didn't break anything. 
+4. Handle failures: If any job fails, the logs will provide information on what went wrong. 
+5. Rerun jobs: If the failure seems unrelated to your changes (e.g., due to a temporary external issue), you can rerun the jobs.
+
+## Troubleshooting Guide
+
+If a CI job fails, here's what you can do to troubleshoot:
+
+1. Check the logs: The logs provide detailed information on what went wrong during the execution. This is your starting point.
+2. Reproduce the issue locally: Pull the relevant container image and rerun the script that failed. This will allow you to dig into the issue in depth.
+3. Fix the issue: Once you've identified the problem, you can make appropriate changes to your code and rerun the CI jobs.
+
+### How to Reproduce a CI Failure Locally
+
+When a build or test job fails, it will provide instructions on how to reproduce the failure locally using the exact same code and environment used in CI.
+
+For example, here is a screenshot of the log of a failed build job:
+
+![Build Job Failure](docs/images/repro_instructions.png)
+
+This provides instructions for both a command-line and a VSCode-based approach to reproduce the failure locally.
+
+When interating on a fix, the vscode devcontainer approach is recommended as it provides a convenient, interactive environment to debug the issue.
+
+## More Information
+
+You can refer to [GitHub Actions documentation](https://docs.github.com/en/actions) for a deeper understanding of the process and the [GitHub Actions workflows syntax](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions) to comprehend the workflow files' structure and syntax.
+
+You're not in this alone - the community is here to help. If you're stuck, don't hesitate to raise an issue or ask for assistance. Open source thrives on collaboration and learning. Happy coding!
